The Home Infusion EDI Coalition (HIEC) Resource Center

Standardized electronic claiming and coding for home infusion is one of NHIA's top priorities and our hard work on this important issue brought about a significant victory in 2001 when the federal government's HCPCS administrators published national standardized coding for home infusion therapy services effective in January of 2002. Since then, the HCPCS per diem S-code system has been widely adopted by commercial payers and some government payers throughout the nation. These codes are compliant with federal Health Insurance Portability and Accountability Act (HIPAA) regulations that mandate that all public and private payers use "approved" standardized coding for all of their health care transactions.

To help payers and providers of home infusion services comply with these requirements, in January 2002 NHIA released its first version of the educational resource, the NHIA National Coding Standard for Home Infusion Claims Under HIPAA. NHIA updates the National Coding Standard to maintain currency with changes in the national code sets. Obtain the latest version of it below.
